She announced the news on her verified Reddit channel, which was an impressive bit of synergy, we say.

She also came up with a little poem for the occasion, writing: "I came home a little late. Someone had a bag packed for me. And a carriage awaited. Destination: Rome. To escort me to my very own 'charming'. Back to where our stars first collided. And now it was full circle.

"At the same table we first met by chance. This time he made it not by chance but by choice. Down on one knee, he said 4 words. And I said yes."

Later in the day, a spokesperson for the tennis star confirmed the happy news to TMZ.

Currently ranked at number 2 in the world, Serena won the Australian Open in January but hasn't played since she beat her sister Venus in the final. We're assuming there's no more competitive tennis on the near horizon, although she hasn't officially confirmed that.
